    blast area safe zones

Graduate Research Experience Radiation Transport
  • Part of a scientific team interested in
    discovering the cause of supernovae
  • Radiation transport involved in key processes
    taking place in supernovae
  • Radiation transport describes processes that
    occur when the properties of protons are altered
    by scattering, absorption, and reemission of the
    matter through which the protons are passing

Graduate Research Experience contd
Integro-differential form of Boltzmann Radiative
Transfer Equation
  • Equation extremely difficult to solve because of
    the integration on an angle
  • Scientist uses Discrete Ordinates Methods to
    circumvent this
  • DOM divides the domain into regions called
    ordinates through discretization

Discretization of integration over an angle by
quadrature sums times appropriate weights at
finite points in interval
Radiation Density Visualization
Radiation Density Relief
Time Derivative of Radiation Density
Summer Research Summary
  • Provide scientist with tools to explore radiation
    transport data
  • Interest in remote distributed visualization
  • Chose this work in order to gain experience in
    scientific visualization and to better understand
    needs and challenges of visualization first

Scientific Visualization Definition
  • Visualization is a method of computing. It
    transforms the symbolic into the geometric,
    enabling researchers to (more effectively)
    observe their simulations and computations.
    Visualization offers a method for seeing the
    unseen. It enriches the process of scientific
    discovery and fosters profound and unexpected
  • -B. McCormick, T. DeFanti, and M. Brown

Scientific Visualization Rationale
  • Has promise as method of interpretation and
    navigation through huge amounts of data
  • It is estimated that 50 of the brain's neurons
    are associated with vision. "The purpose of
    scientific computing is insight, not numbers."
  • - Richard Hamming,1982.

Principles of Scientific Visualization
The scientific investigation model as it relates
to scientific visualization
Distributed Systems Computational Grids
  • Can support the execution of large-scale,
    resource-intensive, distributed applications
  • Distributed systems
  • Linking resources in a geographically remote

Distributed Systems Computational Grids
  • Example of an e-ChemLab enabled by grid technology
  • Spring 2004 special topics course on grid
  • Instructed by Drs. Geoffrey Fox, Bryan Carpenter,
    and Marlon Pierce from Indiana University

Distributed Visualization Architecture DiVA
Distributed Visualization Motivation
  • Resources and capabilities for visualization are
  • Large data store may be at one site
  • Special display system at another
  • High graphics performance processing capabilities
    may exist at a rendering farm in another site
  • What if we could create a system to take
    advantage of all these capabilities in an
    application that works seamlessly as a single
  • Remote distributed visualization (RDV) can enable

Distributed Visualization
  • Applications
  • Particle Physics
  • Astronomy
  • Genomics
  • Bioinformatics
  • Computation Biology
  • Any scientific domain that generates huge amounts
    of data and can take advantage of high
    performance computing

Distributed Visualization Architecture Remote
Distributed Visualization
  • Key Problem Areas in Remote Distributed
  • New Network Transport and Communications
  • Job Control
  • Brokering of Grid Services for Visualization
  • Common / Unified Data Formats
  • New Visualization Algorithms

RDV Need for a Broker
  • Possible to manually configure a RDV application
    on limited number of machines in a distributed
  • Infeasible with many ( hundreds ) of machines and
    components not to mention that one would have to
    know all the info about each component
  • This needs to be automated could be done by an
    agent called a broker

Visualization Services Broker
  • A Broker provides services for
  • Service/Component Discovery Location
  • Performance Prediction / Modelling
  • Optimal Configuration
  • Application Invocation
  • Permissions Granting / Acquisition
  • Recording Performance History / Configuration

Research Plan
  • Tentative Thesis Topic Area

    visualization, and distributed computing.
